This'invention relatesto" surgical pads and V has for its object the production of-a device Y The annular member 15' may of this character which is provided with an annular inflatable portion adapted to be bound against the body of a person andsurround a wound, therebyforming a complete seal around a central pocket from which liquid matter exuding from the wound is adapted to drain off through .a tube to any suitable receptacle.

This object is attained by the mechanism illustrated in the accompanying draw ng.

For the purpose of illustrating the inven-. tion, one preferred form thereof is illus-- trated in the drawings, this. formhaving been found to give satisfactory and reliable; results, although it to be understood that 1 the various instrumentalities of which the invention consists can be variously arranged and organized,and the .invention is notlimited to the precise arrangementand organization of these lnstrumentalities as herein shown and described except. as required by the scope of the appended claims.

Of the drawings i Figure 1 represents a plan of a padembodying the principles of the'present invenbe mmovable in said tube'andvasealiwwill tion. 7 y

Figure 2, represents an inverted plan I the same, and i t Figure 3 represents a vertical section of same on line 3, 3, on Fig. 1.

Similar characters indicate like parts throughout the several figures of the drawing's.

In the drawings, 10 is a rigid disk the opposite sides of which are covered with sheets 11, 12 of rubber or similar material. 7

The outer side of the disk 10 has a strap 18 secured thereto by strips 14:, this strap 13 providing a means whereby the disk may be secured to a bandage, belt, or othersecuring means.

' As this securing means forms no part of the present invention it is deemed unnecessary to show the same or how it is secured to the disk 10.

The opposite side of the disk 10 has socured thereto an annular member 15 which is made of stretchable material such as rubher.

be of any desired shape in cross section and owing to its annular shape a pocket 16 is formed within its inner cylindrical wall 17 as shown in Figs. 2 and 3. I

' between the inner wail 17 was outer-cylindrical wall 18 extends a flexible stretchable tube1 9'Lthroughfwhich a catheter'or similar draining device-2O adapted to be inserted,

as shown inFigl 3;

This tube orfpassage is secured at its outer ends by the flanges 21 to the walls 17,

18 in such a manner to be air tight. In o r.

der to obtain the results desired the tube 19 is positioned closely adjacent thev bottom' surface of the. annular member15,'that is,- at. a point as far, removed as possible from the disk 10. I I

,From the member 15 extends aninflating tube 22, the outer end of whichis provided with a valve member 23 having a threaded portion to which anywell knownair com pressor may be applied.

. lhenit is. desired Ito usethe pad the disk 10 by means of strap 13 is secured to a band age or similar device and thenthe member 1 15 is inflated with" the catheter 20 in the tubular passage 19.

VVhenthe member 15cisfinilated the air pressure therein will force the wall of thetube 19 into such close contact with the pe-' riphery of thecatheter that the latter will injured part of a person with the pocket 16 over the sore, wound or incision, the in flated member 15 keeping all portions of the device 'free from contact with that portion of the body.

By wrapping the bandage tight the inflated member 15 will yield sufficiently to conform to the contour of part about which it is wrapped, thereby making a perfect seal between the pad and the body so that there can be no escape of liquid from the pocket 16 except through the catheter 20.

Vhen thus in use the tube 22 when the inflation has been completed is tucked into the folds of the bandage when it will not come into contact with the body of the injured or sick person.

While in many cases the draining of a wound or a sac of the body may be drained through a catheter inserted into an incision,

there are other cases where this would be impossible owing to the particular character of the wound or incision. H

In these latter cases the present invention annular member will be flattened so that the catheter will be closely adjacent: the

is used. allowingthe liquidwithin a sac of the body orothenmatterto" pass from--the body into the pocket 16 from which itmaybe drained ofl' through=thecatheter into. a

receptacle provided for such drainage.

hen an incision is beginning to heal: ity

is obviously essential thatthe draining tube must be removed from-tlie incision and during this healing, the pad of. the present invention is used, collecting i'nthe pocltet'l6 any liquid exuding fromthe incision:- When the device is in use the bottom of the body 'of'the "patient and all pus or other matter coming; from the: wound will be drained, o'if permitting the wound to heal more" readily; The catheter 2O'f1nay be so adjusted? in the tube 19and 'so retained therein that its innerf end" will never contact-'with the patients body to cause irritation andi pree- 'VGIllJ, thequick healing of the wound.

Thedisl'r .10 is of such rigidcharacten that it prevents bed clothes andall other articles coming intocontact with the injured part ofthe body.

By means ofthis device the bodyofqthe patient iskept' freefr'om all liquid coming from tli'einterior ofthe body.

'Whenaibandageis unnecessary, a; strap or belt of usual"construction may be'inserted beneath the strap 13 and betweenthe strips 14 and the pad; secured in position; by passing'; the strap or belt around the" body andsecuring together the opposite'end's thereofi It believed thatftheoperation and many' advantages of the invention will? bev under-- stood" without furtherrdescription;v
